Look at the changelog for gas:

2002-07-25  Richard Sandiford  <rsandifo@redhat.com>
        * doc/c-mips.texi: Remove -mcpu.  Document -mabi.

http://sources.redhat.com/ml/binutils/2002-07/msg00257.html
also says:
- -mcpu was deprecated in the last GCC and GAS releases.  This
  patch removes it.

http://sources.redhat.com/ml/binutils/2001-07/msg00010.html
is where -mcpu was deprecated as a commandline option to as.

So I guess you have two choices: either fix your sources to
use -mabi instead of -mcpu (I think; I'm no MIPS expert,
you might ask a MIPS linux mailing list),
or step back to a binutils from before July 2002.  Maybe
binutils-2.12.1.  What version is in your downloaded toolchain
(and where did you download it from)?
